S.E.C. Accuses 6 of Defrauding A Swiss Bank and Lehman Bros.

The Securities and Exchange Commission accused six people yesterday of masterminding a scheme involving the ''leasing'' of shares in small companies. The commission said they managed to defraud a Swiss bank, Bank Leu, of $3 million, and to defraud Lehman Brothers of $6.5 million.

According to the civil complaint filed in United States District Court in San Diego, the defendants arranged to obtain stock certificates for large blocks of restricted stocks in 18 small companies, 5 of them then listed on the Nasdaq small-capitalization market and 13 traded over-the-counter, either on the Pink Sheets or the Bulletin Board.

The companies, or in some cases executives of the companies, were promised as much as $1 million a month to lease the certificates for a year. The six people were said to have promised they would not sell or otherwise pledge the certificates.

An S.E.C. official said that in some cases the companies were told that having the certificates would enable the defendants to meet certain regulatory rules or make balance sheets of their companies look better. There are no obvious legitimate uses for such a leased share certificate.

Instead, the six people used the certificates as collateral for loans, the S.E.C. charged, and succeeded in getting money from the Toronto office of Bank Leu and the London office of Lehman Brothers.

The six people charged by the S.E.C. were Charles Anthony Ferracone of San Diego; James L. Erickstein of Kamloops, British Columbia; Gary L. Moore, also of Kamloops; James W. Farrell of Sandy, Utah; Jill Hall, also of Sandy, and Guido Bensburg of Miami Beach, Fla. None of the defendants could be reached for comment last night.

The S.E.C. said the defendants had not cooperated in the investigation and that no settlement was expected.
